Preventive oncology is a branch of medical science which focuses on reducing the incidence of cancer and its related deaths by adopting a healthier lifestyle, vaccinations, and detecting cancer through early screenings.
On the other hand, early cancer screening means testing individuals for cancer even before they exhibit symptoms to detect the disease at its earliest stages when they are most treatable. Some common examples of screening tests include:
• Mammography for breast cancer
• Colonoscopy for colorectal cancer
• Pap smear and HPV testing for cervical cancer
• Low-dose CT scan for lung cancer
Who should consider Preventive Oncology?
There are certain individuals who are considered to be at a higher risk of developing cancer. Individuals falling under this category include:
• Those with a family history of cancer
• People over a certain age group (over 40 years)
• Those with lifestyle risk factors (e.g. smoking, drinking alcohol, obesity)
• People with genetic mutations associated with cancer
Some Early Detection Strategies
The role of early detection in cancer prevention cannot be overlooked. By undergoing few detection strategies, cancer can be diagnosed early and treated well.
• Routine check-ups: People in their 40s are recommended to undergo most cancer screenings, especially if they are at a higher risk.
• Targeted screenings: Breast, colorectal, and cervical cancers have high survival rates, if detected early. Emerging technology in cancer screening such as Multi-Cancer Early Detection (MCED) test utilizes blood samples to identify DNA/protein signals from various cancer types.
• Symptom awareness: Being aware of early warning signs of cancer such as unexplained weight loss, changes in bladder/bowel habits, persistent fatigue, unusual lumps, etc. is crucial for timely diagnosis.
Key Benefits of Preventive Oncology and Early Screening
• Improved survival rates: Cancer, if identified early, has greater survival rates than when identified during late stages. Early identification makes treatment easier.
• Less aggressive treatment: Cancer that has been identified during the late stages, need rigorous treatment such as intensive chemotherapy and extensive surgery. When identified early, simpler cancer treatment modalities suffice.
• Lower healthcare costs: Treating early-stage cancer is typically less expensive than cancer that has been detected at an advanced stage. Fewer complex procedures and reduced hospital stays lower the burden of healthcare costs.
• Enhanced quality of life: Early medical intervention leads to faster recovery from cancer, with fewer complications. The patients are able to maintain a more normal and healthier lifestyle.
• Better risk management: By using the tools of preventive oncology and early screening, individuals with high genetic and lifestyle risk can be identified. This can happen when such individuals proactively undergo preventive monitoring and follow strategies for cancer prevention.
As awareness around cancer prevention grows, preventive oncology is fast becoming an integral part of healthcare systems around the world. While preventive oncology works around identifying risk factors, promoting healthy lifestyle choices, and implementing screening programs, early screening tests are designed to identify abnormal changes in the body even before symptoms appear. With advancement in medical technology and research, preventive oncology and early screening will continue to remain key pillars in protecting public health.
